STEAM SANDER AND CRYSTALLIZING-MACHTNE.

To all whom it may concern:

Be it known that I, SVEN A. HALLBERG, a citizen of the United States,residing at Chicage, in the county of Cook and State of Illinois, haveinvented-certain new and useful Improvements in Steam Sanders andGrystallizing-Machines; and I do hereby declare the following to be afull, clear, and exact description ofthe invention, such as will enableothers skilled in theart to which it appertains to make and use thesame.

This invention relates to confectionery machines and as its principalobject contemplates the provision of a machine for mechanically sandingand crystallizing gum drops.

It has heretofore been necessary in preparing gum drops or other similarconfectionery for the market to perform by hand or by some fewindependent mechanical means the various steps and processes necessaryin sanding and crystallizing the gum.

This invention therefore aims to provicle'a unitary plant for performingall the necessary steps in sanding and crystallizing the gum from thetime it is received from the starching machine until it is a finishedprocluct, ready for the market.

A further object of this invention resides in the provision of means forprogressively steaming,sanding and crystallizing the gum.

A yet further object is to construct the sanding'device in such mannerthat all eX- cess sugar applied to the gum in the sanding operation isautomatically conveyed to an elevatorby which it is carried again to thesanding chute for reapplication to the gum.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out -in the claimswhich are appended hereto and form a part of this application.

Vith reference to the drawings, wherein I have illustrated the preferredembodiment of my invention as it is reduced to practice, and throughoutthe several Views of which similar reference numerals designatecorresponding .parts: Figure 1 is a side elevation of the machine; Fig.2 is a section on the line 22 of Fig. 1; Fig. 3 is a section on the line3+3 of Fig. 1; and Fig. 4 is a sec- Specification of Letters Patent.

tional view illustrating the means employed for adjusting the elevationof the steam jacket.

Proceeding now to the description of the drawings, this inventionincludes three main elements designed to successively steam sand andcrystallize the gum.

Steamer.Taking up the three elements in the order named, the steamer ofthe machine includes a preferably cylindrical steam jacket 1 fixedlymounted in any suitable manner in a frame designated as an entirety inFig. 1, by the numeral 2. The jacket 1 has a steam connection 1communicating therewith. The frame 2 consists essentially of a pair oflongitudinal beams 3, and a pair of cross beams 4. The members 3 arepivotally mounted at their forward ends, as at 5, to the upper terminalsof the vertical supporting leg 6 of a main supporting frame 7, asillustrated in Fig. 1. The frame 7 includes the vertical legs 6 and 7the longitudinal beams 8 and 9, and cross beams 10 and 11. As a meansfor adjusting the inclination of the steam jacket 1, the frame'2 hasbeen fixed only at the forward end, as above described, and isadjustably supported at its rear terminal through the medium of athreaded rod 12 attached by a bolt and socket joint at its upperterminal, as at 13, and operating through a suitable slot 14 formed inthe cross beam 11 and beveled bed-rock 14 mounted thereon. The rod 12operates in and is supported in the desired position by an internallyscrew threaded collar 15 carrying the laterally extending radialsupporting arms 16, the free ends of which ride in arcuate slots 17formed in the member 7, as is best illustrated in Fig. 4.

Rotatably mounted within the steam jacket 1 is a conveying drum 18,preferably formed of copper wires, although any other suitableforaminous metallic material may be used. The member 18 is fixed in anydesirable manner on a shaft 19 journaled at each terminal in bearingstandards 19 and 20, carried by the frame 2. The forward end of theshaft 19 is equipped with a bevel gear 21 disposed to mesh with asimilar gear 22 keyed on a counter shaft 23, which latter member is journaled in bearing standards 24 and is driven by a belt connection 2 1by a motor 25, or any other desired power source. On its lower side, andat the forward end thereof the jacket 1 is provided with an escape chute26 arranged to c011- duct the steamed material from the drum 1 into thesanding mechanism. to be next de scribed.

Before proceeding to the description of the sanding mechanism, it isdesirable to explain briefly the operation of the steamert The gums arepoured into a hopper 27 from which they pass into the drum 18 at' becontrolled both by regulation of the temperature in the steam jacketand'by ad ustingthe frame 2 at various angles of inclination to effect arapid or slow passage of the gums through the drum 18in the manner abovedescribed. i

' TScZmZer..-Following the steamingprocess,

the gums are put through the so-called sanding process, which consistsessentiallyln applying granulated sugar to the gums. As" a means formechamcally sanding the gums,

there has been provided a sanding chute 28 communicant at its upperterminal with the sand buckets 29 of the apron elevator 30,

and communicant at its lower terminal with; an angular-1y disposed chute31. The ele-- be mclosed 1n a. caslng 32,.

vator 30 may 7 although this feature of the lnventlon is an unimportantone,'1nasmuch as any suitable type of elevator may be employed withoutdeparting from the spirit of this invention; As the gums pass throughthe chute 31, the I sugar issues from the chute 28 covering the goods.The elevator is operated by a belt At'its lower connection to the motor25. terminal the chute 31 communicates with a cylinder 32 supported on.a frame 33 and formed. throughout the greater part of. its length ofsheet 'metal, being constructed, however, at its forward end ofcopperscreening or other suitable foraminous ma terial 36 for a purpose to behereinafter described. Within the cylinder 32is rivetedor otherwisefixedly secured a progressive worm vane 34 carried on a shaft 35 whichis journaled in the ends of'the cylinder. It

will thus be seen that actuation of the shaft 35 rotates the cylinder 32and. worm 34: to-j At its forward" end and immedi gether. atelybelow themember 36' 'ofthe cylinder 32 is arranged an escape funnel 37 adaptedto-conduct all excess sugar from the cylinder 32 into thelower portionofthe ele-, vator from whence is again conducted the buckets 29 to thesanding chute 28., The shaft 35 is mounted in suitable bearings 38carried by the "frame 1 '33 arid is fdriv en by a terminal-bevel gear39, which meshes with a similar gear 40 keyed to the shaft 41. Theshaft-4:1.is-operatively connected through the drivepulley 42 by a beltl3. The member d2m'aybe connected to the driveshaft of the motor 25 inany desired manner.

Grg staZZ izer.As the gums reach the'forward end of j the cylinder 32,they pass through a chuteee into a drying jacket 45, wherein they aresubjected to a high degree of dry heat. preferably; produced .by steampipes .46. arranged within the jacket, 45, Since the steam jacket 1requires a boiler it is'of course more desirable, and economical. toheat the acket 455. by steam plpes con nected to thesame boiler, butinasmuch as condltions concurrent vvlththe adaptioniof,

this machine may vary, the jacketkl 5 has been designed to permit .theutilization of. gas or other dry heat producing fuel. .it is,

or course" apparentlin this. connection that if it is so desirediahotiblastfrom a hot air;

furnace maylbe 'eiriployed; The object-of subjecting thegu1ns,-whicl1.have previously been moistened and sanded, to a high de;

gree of dry heatin the jacketfl5, isof course to' absorb. the. moisture.from the coating of the' gums, thus cry sta1lizingthe' sugarui Thejacket 45 is essentially. a rectangular box,

equipped interiorly with the conveying apron-f7 mounted on rollers 48,.and actuated.

through a belt orchain drive'e9 Q connecting the motor to a driveWheelkeyedto the shaft of the rear roller- 48. Upon, reaching the.

forward end of theacket .45, the gums pass through a discharge pipe4i9beneath which. may be placed shelves or packing boxes 50 The actualconstruction and operation'of the machine being thusldescribed, itnowgremains to enumerate the manyadvantages re-,

sulting from the novel structureiemployed in the preferred embodiment ofthis invention. In this connection it is to be observed that thisinvention comprehends a' lnitary plant for sanding and crystalhzmg gumdrops,

operating to subject, the gums to the three processes ofsteaming,sanding and :crystallizing. Attention is also directedfto thefact that the wastejof sugar in the sandingproc'essiis avoided byproviding, means for reapplying the: extra. su'ga'r tov the gum Y 1 3 iK In reductionto practice, I have found that drops.
